WRENCH.

Specification of Letters Patent.

Application led January 29, 1920. Serial No. 354,929.

T 0 all 107mm 'it may concern:

Be it known that l, 'WiLLrAM B. BANDY, a citizen of the United States, residing at Crossville, in the county oi Cumberland and State oi Tennessee, have invented certain new and uset'ul improvements in llifrenches, oi which the 'following is a speciiication, reference being had to the accompanying drawings.

if his invention relates to wrenches and has for its objeit to provide a device ot this character which adjusts itselic when applied to the work.

Another object is to provide a wrench ot this character including a pair of pivoted jaws carried by a handle, one of said jaws being arranged for oscillating movement and the other for sliding movement.

Another object is 'to provide a wrench oi this character including a pair ot jaws pivoted to each other at theirintermediate portion. the adjacent edges ot each jaw on vhoth sides oi the pivotal connection coperating to torni gripping jaws.

Another object is to provide a wrench ot this character having a nut threaded on vthe handle and Iadapted to engage end ot' the slidable jaw, to hold the wrench adjusted.

lilith these vand other objects in view the invention consists in the improved construction and improvement ot parts to be hereinafter more particularly described, tally claimed and illustrated in the accompanying drawings in which:

Figure 1 is a side elevation oi wrench constructed inaccordance with one torni oit iny invention;

Fig. 2 is a top plan view oi' the wrench shown in Fig. l, partly broken away;

Fig. 3 is an under side plan view;

Fig. d is a section on the line -ei orn Fig. 1;

eterring to drawing 5 designates a handle having its edges 6 threaded and its end 7 reduced to provide an extension 8. rlfhe end 7 is provided with a slot 9 which extends longitudinally of the handle and through the sides 10. Y

Associated with the handle, is a pair oi jaws 11 and 12, the jaw 11 having its ends and intermediate portions urcated to provide arms 13. rlhe end portion 14 ot each arm, extends upwardly in angular relation to the arni and has its extremity 15 extending in angular relation to the portion 111.

The surface 16 of the extremity 15 and the surface 17 of the portions 14 are provided with gripping teeth. A V shaped recess 18 is formed in the side edges of the arms 13 remote from the edges containing the gripping teeth, and at the junction of the end portion 1e with the arm, to provide wire cutting rneans and also an additional gripping surface through the coperation ot' the adjacent edges of the end ot the jaw 12, each arin being provided with a pivot opening 19. The intermediate urcated portion ont the jaw 11 is intended to receive the shank 2O of the jaw 12, the intermediate portion oi the shank 2O is provided with an opening which registers with the openings 19, a pin 22 being passed through the registering openings. The end portion 23 oi the jaw 12 includes extensions 24 on each side thereof, which terminate adjacent the end 25 ot' the shank 20. The end 25 together with a por-V tion of the extensions 2lextends in angular relation to the shank 20, the angular-ly extended portion and the adjacent portion oi the shank being provided with gripping teeth. The ends oi the extensions are intended te engage the side edges of the jaw 11 to limit movement of the jaw 12 toward and away frein the jaw 11, the end 25 ot the jaw 12 being received in the 'urcated end portion of the jaw 11.

The end 26 of the jaw 12 is turcated and adapted to receive the extension 8 of the handle 5, a pivot pin 27 being passed through the end 26 and handle to pivot the jaw to the handle. The threaded end of the handle 5 is intended to be received in the furcation ot the ends 28 of the arms 13. i pin 29 is provided to connect the ends 28 oi' the arms 13, the intermediate por tion oi' the pin 29 being slidably disposed in the slot 9 ot the handle. When the jaws are thus connected to the handle, the portion ot the shank 2O of the jaw 12 adj acent the end 26 thereof coperates with the groove 18 to provide additional gripping surfaces so that two wrenches are provided by the novel arrangement of one pair of jaws.

t A manually operable nut 30 is rotatably mounted on the threaded end 7 of the handle, stops 31 being provided at the end of the threaded portion to prevent disengagenient of the nut 36 from the handle. This nut is rotated on the end 7 into engagement With the ends 28 ot the arms 13 to adjust the jaws to the size desired. ln use, the nut 30 is rotated on the handle so as to move the jaw ll toward the'endof the handle and the jaiv 12and through said movement cause the jaw l2 tormove toward the jaw Vlil and engage the Work; The Wrench is used in the Vusual manner and the same operation oscurs When the Work is engaged by the .toothed recess 18. The nut 30 may be adjusted to cause the javvs to engage the Work but not bind thereon. ln this Way, the VWrench may he used similarly to a ratchet lever, that is, Without requin ingv the handle of the'Wi-ench to revolve with the Work but to revolve the Work step by step. v Y Y F rom the foregoing it Will be Vreadily seen that this invention provides a novel Vforni of Wrench'containing two separate gripping surfaces, one oijvvhich may he used for the purpose of 'holding or cutting Wire. In addition `to the self-adjustingffeature, the Wrench is provided with a nut tor holding the jaws adjusted or foi'permitting the instantaneous self-adjustment of the. jaws on Y small Work, and` alll oi these features are ossessed b a Wrench that is sini le in con- P Y struction. Jlifdesired, another method may Y' be used in adjustingV the Wrench and consists of placing the jaws into engagement `With the Worlra'nd movingthe lever toV one side so as to cause the jaivs to firmly engage the Work. v The nut 8O then Vhe rotated on the handle into firmienaemeiit with the ll. lt will thus be seen end 28 ot the jaw to itsrv'arious uses, the

that in addition VWrench isY also ca able of hein(y ad'usted lov several methods.

What is claimed is: Y Y l. A wrench ofthe vcharacter described comprising a handle having a slot adjacent Vone end, a substantially Leshaped oscillating jaw and a substantiallyfZ-shaped slid-V ing jaw, said oscillating jawbeingpivoted ait one end to the handle adjacent the slot,

Y jaw, said oscillati one end to the handle and having the rear .face thereof ad acent its nivotal connection tion oi' the ing pivoted to each other at the intermedi-` ate portions, the slotted end of the sliding jaw being arranged to straddle the end portion of the handle over the slot therein, a pin extending through said slot and the handle, the ends ofthe extensions oi the oscillating jaw being arranged to alten iiately-engagethe end and intermediate portion of the thereof. Y Y

2.VV A wrench of the character described comprising a handle, there being a slot'eX- tending laterally of the handle, a portion oi' Athe handleV adjacent the slot being threaded, an oscillating jaiv and a slidalole DE ."iW being pivoted at reduced, said sliding jaiv'having its end portions Vextending in the opposite direction to each other and provided with a recess atV thejunction ofV one oi said end portions with theintermediate portion of the jaw, said intermediate and end portions being longitudinally slotted, said'sliding` jaw being` arranged to straddle the'oscillatingV Vjavv at its intermediate portion, said end of the sliding jaw being movable over Vthe slotted 'portion oi" the handle, the recess in the sliding jaw coperating With the Vreduced portion adjacent the pivotal connec- Vprovide additional gripping surfaces, and an internally threaded member rotatable fon the handle for engagement With the threads Yth'ereorn and adapted to operatively engage the end of Vthe sliding jaiv to gradually adV j just Vsaid 1avv's upon movementof'said inem-A Y ber in one direction.
